Problems solved by technology
[0003] When the previous shield machine encounters a lot of irregular hard rock in the underground rock formation ahead, the cutter head of the shield machine wears a lot and needs to be pre-cut. However, the existing technology lacks an experimental platform for the pre-cutting of the shield machine

The invention discloses a high-pressure water jet and hob composition simulation experiment platform. The platform comprises a bottom plate; the upper end of the bottom plate is fixedly connected witha plurality of supporting blocks; the upper ends of the supporting blocks are fixedly connected with a supporting plate; the upper end of the supporting plate is fixedly connected with a simulation test cylinder; a gap rotating mechanism is arranged on the supporting plate; the output end of the gap rotating mechanism is connected with a support; an extensible driving mechanism is installed on the support; the extensible driving mechanism is provided with two output ends, one output end is connected with a water jet and hob installation plate, and the other output end is connected with a supporting rod; a base plate is rotationally connected with the end, away from the extensible driving mechanism, of the supporting rod; and a simulation pressing plate is arranged at the end, away from the supporting rod, of the base plate. The device has the outstanding characteristics that high-pressure water jet equipment and traditional hob equipment can be conveniently installed on the water jetand hob installation plate, and a high-pressure water jet technology is adopted for cutting, so that a simulation platform is provided for a shield tunneling machine.
Description
technical field [0001] The invention relates to the technical field of shield machines, in particular to a simulation experiment platform for combining high-pressure water jets and hobs. Background technique [0002] The basic working principle of the shield machine is that a cylindrical steel component is pushed forward along the tunnel axis to excavate the soil. The shell of the cylindrical assembly is the shield, which acts as a temporary support for the excavated, unlined tunnel section, withstands the pressure of the surrounding soil and sometimes groundwater pressure and keeps it out. Excavation, soil dumping, lining and other operations are carried out under the cover of the shield. [0003] When the previous shield machine encounters a lot of irregular hard rock in the underground rock formation ahead, the cutter head of the shield machine will wear a lot, and pre-cutting is required. However, the existing technology lacks an experimental platform for pre-cutting of...
